Thursday June 28, 2014 – Still in Maryland
We’ve reached our 14 day limit and have to leave Cunningham Falls State Park. We’re moving 20 miles away to Greenbriar State Park, just off Interstate 70 between Hagerstown and Frederick, Maryland. We’ll be staying here for 3 nights then move back to Cunningham Falls SP on Sunday.
Why are we staying so long?
We originally planned a 2 week stay to spend time with my sister who lives in nearby Thurmont. Back in May, I lost a crown and made an appointment with my sister’s dentist to have it replaced. Even though my initial appointment was on Day 1 of our arrival, it takes a couple of weeks for the permanent crown to arrive. If all goes as planned, I’ll have the crown installed Wednesday morning, July 2 and we’ll leave at noon for a stopover in Pennsylvania on our way to Littleton Massachusetts. Littleton is within commuting distance to Boston. We lived there back in the late 90’s and are looking forward to visiting our old haunts.
It’s a good thing we have 2 A/C’s.
It’s been warm the past couple of weeks. The Washington DC area has been in the 90’s and even though we’re in the mountains at 1500 feet, we’re seeing daytime temps in the mid-80s with lows in the upper 60’s. The humidity is high so we’ve been using the A/C at night. Our 30’ Airstream came with 2 Dometic roof mounted A/C’s. Rarely have we needed to run both at the same time and since we only have 30 AMP service at Greenbriar SP, we’re limited to running one at a time. They’re rather loud so we typically run the one at the opposite end of the Airstream from where we’re spending time. Last night while watching TV, the one in the bedroom, i.e. Zone 1, stopped putting out cold air. For some unknown reason, the thermostat is showing an inside temp of 32 degrees for Zone 1. Since the A/C thinks the inside temp is so cold, the compressor will not cut in when running in Cool mode. To test the compressor, I try running the A/C in Heat Pump mode. I hear the compressor cut in followed by hot air so it checks out.
An Internet search shows this has happened to others but offers no clear cause or solution. High humidity resulting in moisture accumulating on various components is mentioned as a possible cause. As suggested, I try reseting the thermostat and reseating the telephone-like wire connectors but Zone 1 still shows 32 degrees. The problem occurred during a period of heavy rain which supports the moisture theory. I call around to the local RV repair shops but the earliest available service appointments are weeks away. It’s a good thing the A/C for Zone 2 is working fine. I schedule an appointment with a repair shop in Massachusetts for the second week of July. Hopefully the A/C for Zone 2 hangs in there.
Friday, June 29 – Mulberry Tree Entertainment
The drive to Greenbriar State Park is only 30 minutes. This park is very similar to Cunningham Falls only the sites are spaced further apart. There’s a tree by our campsite that looks like it’s growing blackberries. Cindy looks it up on the Internet and determines it’s a Mulberry Tree. She reads where Mulberry Trees are critter magnets. We’re seeing all sorts of birds stop in for a bite to eat. Turns out, Mulberries are edible and are used to make Mulberry wine. According to the Internet, Mulberries are known to ferment in the sun and birds can get a little tipsy from eating them. I’m not sure what a drunk bird looks like but the ones we’re seeing look fine.
So far we’ve seen a Cedar Wax Wing, Scarlet Tanager, Nuthatch, Blue Jay, Cardinal, Chickadee and 3 species of woodpecker: Pileated, Downy and Yellow-Bellied Sapsucker. I was able to photograph some these as shown throughout this posting.
The Scarlet Tanager and Pileated Woodpecker only stop by for a few seconds. Since they’re such impressive birds, I’m including some photos I found on-line:
Saturday, June 28 – A/C heals itself!
Just for the heck of it, I check the inside temp on the thermostat for Zone 1 and it shows a reasonable 68 degrees and not the 32 degrees it’s been showing for the past few days. I try running the A/C for Zone 1 and it works! Others on the Internet with this problem experienced this self-healing behavior as well. Sounds like it could have been a moisture issue all along. We’ll continue to use it and keep our fingers crossed but in the mean time, we’ll keep our repair appointment in Littleton just in case….by
